[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0024] The following describes a large motor rotor mount according to an embodiment of the present invention in detail with reference to the accompanying drawings.

[0025] Example 1

[0026] For easier understanding, please refer to Figures 1 to 4 An embodiment of a large motor rotor mount provided by this utility model includes a base 1, a support column 2 fixedly installed on the top of the base 1, an mounting plate 3 installed on the top of the support column 2, and a plurality of support mechanisms provided inside the mounting plate 3.

[0027] The support mechanism includes a threaded rod 8, two support plates 9, two second connecting seats 15, and two mounting seats 10. The mounting seats 10 are fixedly installed on the top of the mounting plate 3. One end of the support plate 9 is rotatably connected to the inside of the mounting seat 10. A first connecting seat 13 is fixedly installed on one side of the support plate 9. A movable groove 6 is opened on the top of the mounting plate 3. The threaded rod 8 is rotatably connected to the inside of the movable groove 6. The second connecting seat 15 is slidably connected to the inside of the movable groove 6. A connecting rod 14 is rotatably connected inside the second connecting seat 15. The other end of the connecting rod 14 is rotatably connected to the inside of the first connecting seat 13.

[0028] It should be noted that there are several movable slots 6, and the threads on the side walls of the threaded rods 8 in two corresponding movable slots 6 are opposite, so that when the threaded rods 8 rotate, the second connecting seats 15 in the two movable slots 6 can move in opposite directions at the same time. This allows the angle of the support plate 9 to be adjusted, so that the support plate 9 can adapt to large motor rotors of various sizes. The large motor rotor can move on the support plate 9 by contacting it, so that the large motor rotor can be directly placed on the support plate 9 after being removed, thus improving maintenance efficiency.

[0029] In some embodiments, such as Figure 1As shown, the second connecting seat 15 has a threaded hole 16 inside, which fits with the threaded rod 8. The second connecting seat 15 is movably connected to the threaded rod 8 through the threaded hole 16. A servo motor 7 is fixedly installed on one side of the mounting plate 3, and the threaded rod 8 is fixedly installed at the output end of the servo motor 7.

[0030] It should be noted that the servo motor 7 can be used to control the rotation of the threaded rod 8, and the rotation of the threaded rod 8 can be used to adjust the position of the second connecting seat 15 inside the movable slot 6.

[0031] In some embodiments, such as Figure 3 As shown, the support plate 9 has an installation groove 11 inside, and a support shaft 12 is rotatably connected inside the installation groove 11.

[0032] It should be noted that by setting the support shaft 12, the large motor rotor can easily slide on the support plate 9 during the removal process, making the removal process of the large motor rotor more convenient.

[0033] Example 2

[0034] In some embodiments, such as Figure 1 As shown, a first hydraulic cylinder 4 is fixedly installed inside the mounting plate 3, a top plate 5 is fixedly installed at the output end of the first hydraulic cylinder 4, a second hydraulic cylinder 17 is fixedly installed at the top of the mounting plate 3, a fixing plate 18 is fixedly installed at the output end of the second hydraulic cylinder 17, and a support pad 19 is fixedly installed inside the fixing plate 18.

[0035] It should be noted that the first hydraulic cylinder 4 can be used to control the lifting and lowering of the top plate 5. The lifting and lowering of the top plate 5 can be used to support and limit the shaft of the placed large motor rotor, and to fix the removed large motor rotor for easy maintenance. The second hydraulic cylinder 17 can be used to adjust the height of the fixing plate 18, thereby supporting the side of the large motor rotor, so that the support pad 19 can support the large motor rotor.

[0036] In this utility model, the first hydraulic cylinder 4, the second hydraulic cylinder 17, and the servo motor 7 are known components and will not be described in detail here.

[0037] Working principle: During use, the base 1 is placed on one side of the large motor. During the removal of the large motor rotor, it is placed directly on the support plate 9. The large motor rotor is moved on the support plate 9 by pulling it. The support shaft 12 makes the movement of the large motor rotor on the support plate 9 smoother and less prone to damage. After the large motor rotor is removed, the first hydraulic cylinder 4 drives the top plate 5 to move. The lifting and lowering of the top plate 5 can be used to support and limit the shaft of the placed large motor rotor. Then, the second hydraulic cylinder 17 drives the fixing plate 18 to move, thereby supporting the side of the large motor rotor and fixing the removed large motor rotor for easy maintenance.

[0038] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
